My invention relates to improvements in window screens, and has for its primary object a window screen composed of two frames having a metal frame interposed therebetween, this metal frame effectually prevents warping of the screen and also prevents it from becoming out of shape. rThis is a feature which frequently happens with window screens of the ordinary window frame construction since in the handling of them they are liable to become twisted out of shape, that is the corners will no longer be square and their entire frame will assume a diamond shape. This not alone makes the screen hard to fit into windows but also stretches and distorts the wire cloth so that it no longer presents a neat, tight appearance but is loose and bulges.

A further object is to construct a window screen which is re-inforced and which can he 0 readily taken apart for recovering with wire cloth in the event the same should become broken.

In the drawings:

Fig. 1 is a face view of my improved screen Fig. 2 is an edge view of the same;

Fig. 3 is a face view showing one of the frames removed;

Fig. 4 is an inside face view of the removed frame showing the manner of attaching the wire cloth thereto;

Fig. 5 is an enlarged fragmental longitudinal section showing the manner of securing the various frames together;

Fig. 6 is an enlarged perspective view of one corner of the metal frame illustrating one manner of securing the same together; and

Fig. 7 is an enlarged fragmental view of one of the corners of the wooden frames showing one manner of securing them together.

In the construction of my device, I employ a pair of frames 7 and 8. These frames are of identical size and are secured together at their corners by means of corrugated brads 9. This, however, is only one manner of securing the corners as they may be secured together by any means well known in the joinery art, that is either by dowels, mortise and tenen or similar securing means. Between :these frames 7 andSis placed :a metal frame composed of strips 10a-nd 11. These strips .are preferably lappedattheirends and spotwelded as illustrated in Fig. 6 although, if desired and .found more convenient., other fastening Vmeans vmay be xused.

The members 10 .and 11areprovided with tapered openings 12 which receive .the heads of the screws 13. These screws .are for .the purpose of securing the :frame to .the .metal frame. The metal frame xis .also `provided with openings 14' which .are locatedy .intermediate the openings 12. -Concentric with the openings 14 are openings '15 which are formed through the .frame 8 .and which rey ceive screws 16. These screws `extend finto the Yframe 7 and are for the purpose of securing it in position on the metallic frame.

The screen cloth 17 is secured ,to the `frame 7 by means of `tacks or similar `fastening means l18. The Ametallic 'frame Vis preferably wider than the wooden frames ,so as to leave a projecting edge or flange ventirely around the frame as illustrated in F igs.1 and 2. 'In 'this way the -top vand bottom edges or flanges .make a close joint :between the. wini dow :sill and the upper window while .the side edges bear against the parting strips which are between the two windows or the vertical f edges can '.be inserted ina grooved strip and 80 act as slides so that the window can `be moved upward vand downward.

The window screen may also h'e fastened on to the window frame by Vmeans of hooks, hinges or the like. In fact my structurelends itself to any of the well known mountings i for screen windows that are used at the present time. l may also, Yif desired, make the face of the metallic 'frame of the same width as the wooden frames without `departing from the spirit of my invention.

My device is assembled as follows: Afterthe various 'frames have vbeen made, the frames 7 and `8 being preferably of identical size, fthe metallic .frame 'is assembled and `95 secured .at .its `corners ,so ythatits .opening will be of the samesizeas the frames .7-andf8. .The openings L2 .and 14 fare `.then formed in the metallic iframe Vand the frame Aplaced :on the wooden trame .8 ,so that 1the openings of both Y the opposite face by means of the tacks 18.

The frame 7 is then placed on the metallic frame with the wire cloth next to the frame and with its opening in alignment with the openings of the metallic frame and the frame 8. The fra-mes are then held together and inverted so that the frame 8 is uppermost and the screws 16 placed in position. In this y manner all three frames are firmly united and by reason of the metallic frame being located between the two wooden frames, all possibility of these frames becoming misshapen, due to rough handling etc., is eliminated. Should the screen cloth become broken or need replacement, it is only necessary to remove the screws 16 after which the frame 7 can be lifted from its place, the old screen cloth removed, and new cloth put in its place after which the frame is again secured in position, as before described.-

Having fully described my invention, what I claim is j 1. A window screen comprising a rectangular metal frame having spaced apart openings formed therethrough intermediate its edges, certain of said openings being countersunk on one face of said frame, a wooden frame of less Width located on one face of said metallic frame, fastening means extending through said countersunk openings of the metallic frame and into the Wooden frame .for securing the same together so that there will be no projections on the metallic frame, a second wooden frame of the same size as the first mentioned wooden frame, a screen cloth secured to said frame, and fastening means passing through said first mentioned wooden frame, the remaining openings in the metallic frame and into the last mentioned wooden frame so that said last mentioned Wooden frame is secured to said metallic frame on the face opposite that to which'the first mentioned wooden frame is secured thereby forming a double wooden frame having an inter- Y mediate outwardly'extending metallic projection. extending entirely around said frame.

2.' A Win dou7 screen comprising a rectangular metallic frame havingspaced apart openings formed therethrough intermediate its edges, certain of said openings being countersunk on one face of said frame, a wooden frame of less width located on one face of said metallic frame so that said metallic frame will project beyond the outside edges thereof, fastening means extending through said countersunk openings in the metallic frame for securin said metallic frame and wooden frame toget er, a second wooden frame of the same size Vas said first mentioned wooden tallic frame, fastening means passing through said first mentioned wooden frame, the remaining openings in the metallic frame and into said last mentioned wooden frame so that when all of said frames are secured together, a double wooden frame with a metallic flange projecting outwardly intermediate said frames is formed and asheet of screen cloth interposed between said last mentioned wooden frame and said metallic frame.

.In 'testimony whereof I have affixed my signature.
